Patented G-Flex Technology allows the Generac Synergy home standby generator to vary its speed based upon electrical demand. It will run slower - and quieter - when you use less electricity. And during its weekly exercise, you’ll hear only about as much sound as if you were riding in a luxury car. The Synergy also consumes less fuel when electricity demand is light, saving you money. And G-Flex technology delivers electricity with less than 2.0% total harmonic distortion (THD) - lower than IEEE standards for utility power - to properly power modern electronics and sensitive appliances. Your Generac Synergy generator might have to get you through days - or weeks - without utility power. Generac’s OHVI engine, specifically designed for generator use, provides the reliability to power through the most severe outages. Evolution Controller, the next generation of intuitive controllers featuring a multilingual, two-line LCD text display with color-coded, backlit buttons. Mobile Link Cellular Remote Monitoring - check on your generator’s status even when you are away with Mobile Link cellular remote monitoring. Use your computer, tablet, or smartphone. Downloadable app available for iOS and Android. Comes standard with Generac Synergy. Third-party certified to NFPA standards to be installed as close as 18" from the home’s exterior wall, provided it is located away from doors, windows, and fresh-air intakes, and unless otherwise directed by local codes. Durable powder-coat finish helps make the sturdy aluminum (gray) enclosure perfect for all weather conditions. It’s also able to withstand 150 mph winds. Tool-less fuel conversion, the Generac Synergy runs on natural gas and LP fuel, and easily converts during installation without the need for tools. Quiet-Test Mode, G-Flex technology allows the Generac Synergy to run at a very low speed during its periodic exercise. You’ll hear about as much sound as you would riding in a luxury car. Select weekly, bi-weekly or monthly for just 5 minutes. Power outages don’t always occur during normal working hours. That’s why Generac’s customer care call center, in Wisconsin, provides support any time of day or night, all year long. Generac is standing by 24/7, every minute of every day, to answer your questions. 5 year limited warranty. Generac's Managed Whole House Transfer Switch is included with this generator. 200 amp open transition switch in single phase, service rated configuration. Gain up to whole-house coverage through smart power management. If it is unlikely you will turn on every appliance at the same time, a smaller generator paired with a Generac Smart power management transfer switch provides whole-house coverage through a managed power solution. The process is simple - non-essential circuits are shed when the generator approaches maximum capacity to eliminate overload, then are cycled back on when essential circuits are satisfied. Give yourself a little more than just the basics without a substantial increase in your investment. All Synergy Smart Switches are housed in an aluminum NEMA/UL Type 3R enclosure, with electrostatically applied and baked powder paint. It is a UL recognized device, designed for years of service. The control at the generator handles all the timing, sensing and exercising functions. The Power Management Module is also included. They work with your transfer switch, monitoring each selected circuit and automatically supplying power where it’s needed so you can get the most from your generator.
